Application filed December 31, 1910. Serial No. 600,313.l

To all whom t may concern.'

Be it known that I, LAWRENCE A. SUBERS,

a citizen of the United States, and resident/ nated-cohesive interwoundfabric can be constructed such as described in my former ap- No. 540,982led January 3l, 1910.

The essential features of novelty contained in this invention are aflattened band originally of cylindrical form, said band composed ofgroups of loose lying parallel yarns or threads cohering together, thisbafn'd being coated on the exterior surface and also thoroughlysaturated throughout the interior with preferably vulcanizable liquidrubber cement or any other suitable adhesive material. These loose lyingparallel yarns or threads are wound as a unit on spools or tubes withoutbeing twisted together and the yarns may be used in anypredeterminednumber in each band, and the tubular band made therefrom will be'ofcorrespondingly predetermined diameter before flattening. This collapsedband has therefore selvage edges, is strong and flexible and whenincorporated in a fabric or when used as a Yfabric in itself will notravel or permit of the separate threads being unwound or separated inany manner under rough usage' and hence assists greatly in prolongingtheflife of the fabric and increasing 'its utility and efficiency indaily use. VThe band can be made of any desired width forincorporationin a laminated, such bands interwound and` 'cohering together. .l

The invention is illustrated in the accompanying drawings, hereinafterfurther described, and specifically pointed out in the claims.

In the accompanying drawings Figure 1 is a plan view of oneside of thecompletedband showing the coating removed; Fig. 1 is a view of a groupof loose lying parallel yarns or threads; Fig. 2 is v.a side'elevationnated a pneumatic tire showing) unwoven fabric composed. ofl

of Fig. 1 showing the coating stripped from a portion thereof; Fig. 3 isa transverse secf tion thereof enlarged; Fig. 4 is a transverse sectionof a forming tube and pressure rolls, illustrating the manner offlattening the tubular form of the fabric band and of saturating thefabric bandwith Vfluid rubber; Fig. 5 is an isometricperspective Viewand illustrates themanner of forming a lami- `unwoven fabric frominterwound bands of this character; Fig. 6 isfa plan view of a portionof the saine fabric after completion; Fg.6a is a perspective Viewv ofthethreads of a Vfabric. band showing manner of formation; Figs. 7 and`8 represent plan views of portions of the band enlarged Q' showing thethreads running at various angles'. for reasons hereinafter' described.Fig. 9 1s a broken side elevation of a `portion of hose pipe formed ofthe improved bands,-

illustrating thestrengthy and durability of exposed parts; Fig. l0`is aside elevation of 'I fabric formedin the same manner as the andi;, Fig.llis a transverse section thereof. i

As shown in Figs. 1, 2, 3, and -4 the bandyis composed of seriesofgroups of close lying parallel yarns or threads. These groups :ofthreads are applied upon aformer D (shown c in Fig. 4') in such avmannerthat they are laid in parallel spacedrows, first in rows running in one.direction and then in rows running at an angle thereto,.followed by rowsparallel/to the first and second laid rows. The spaced threads ofthe'outer rows are compressedto ll the spaces betweenthe I parallel rowsbeneath, the result being an unwoven laminated band of tubular' form,

-in two layers. The fabric l.formed therefrom is similarly constructedas shown in Fi 5,

which will serve also as an illustration o the structure of the bandbutnot of the mode' of kflattening or vof applying rubber thereto.

InFigLh, 1, l and 1,.1, are parallel? bands, running in one direction,and 2,2, 2, and 2', 2', 2, are parallel bands running in --anotherdirection. When compressed theV parallel bands 1 .will come to the samelevel bet-Ween the'other bands l5 andthe bands2 between the b ands'2anda practically twoI ply "fabric Awill result.V c

'The bands are formedof threads B laid in precisely the same mannerasthe fabric, l

and this constructionis shownjin Fig.- 6,v`

3, 3,3, being. parallel threads inthe` upper row '3,'3, Sthelower'rowsparallel therevcal or collapsed form as ma with. fl, l, .4, are the rowsof threads crossing the first named rows and 4;', 4, d are the rowsparallel therewith. The bands having been completed in a former F in adry state in a tubular form are then pulled from the former, `andattened between rollers such as E, E in Fig. 4.

The band is simultaneously saturated with rubber. rlhis is accomplishedin the most thorough manner by injecting the rubber through the formerwhere the pressure of the flattening rollers forces it'into the banduntil it permeates every 4part thereof between the yarns, and coats theyarns and threads in a thorough manner.

The flattening of the tubular band results in the formation of a bandsuch as shown in Fig. 3 of great flexibility and strength and an outerrubber coating G is then applied in any convenient manner or it may becoated while being constructed into a fabric if desired.

It will be seen by reference tol Figs. 7 and 8 that the band can be madeinra similar manner of any desired width and one set or rows of thecomponent threads in one band may be laid at an angle relative to theVother set or rows making it possible to make bands which vary inelasticity, which will be controlled by the angle of the threads. @nthis account a fabric can be made as shown in Fig. 9 having one layer Xformed of such bands of a given degree of elasticity and having otherlayers Y and Z of different degrees of elasticity and hence thedifference in expansibility due to difference in diameter of the severallayers can be overcome and a hose can be formed of several layers whichwill have the same rat-io of bursting limit,

and a stronger fabric will be constructed thereby.

The advantages of a flat band of' this character and its adaptabilityfor use in the construction of fabrics for various uses is thereforevery great.

It is obvious that these bands can be made multiple by adding successivelayerswof this fabric over one another and that an inner lining may beincorporated within this fabric band the whole retained in a cylindribedesired without departing from the spirit of invention or scope of theclaims.

It is also obvious that this \fabric band may be formed of anypredetermined width and of any predetermined thickness from groups ofclose lying parallel yarns or vthreads and may Joe used as fabric ofitself if so 'desired without departing from the spirit of the inventionor the scopevof the claims. y

It is also obvious that any suitable material fabric or otherwise may beformed or laid partially around the mandrel and thereby be incorporatedwithin this fabric bandv during the formation of the same.

Having described the invention what I claim as new and desire to secureby Letters Patent is:

l. As an article of manufacture, a band for incorporation in a fabric,comprising, a

flattened tube composed of unwoven interwound groups of close lyingparallel yarns or threads, arranged in parallel rows, and the sidesofthe tube compressed together to -form selvage edges, the said bandsaturated with fluid rubber or other adhesive material.

2. A band for incorporation in a fabric, comprising, a tubularstruct-ure composed of threads formed from groupsv of close lyingparallel yarns or threads, said groups of threads laid in spacedparallel rows at predetermined angles crossed by spaced groups ofthreads laid at predetermined angles' thereto, a row of said spacedgroups of threads filling the spaces between the rows of groups ofthreads parallel therewith, the sides o-f said tube being flat-tenedtogether and saturated with fluid rubber or other ad hesive material andan exterior coating on said band.

3. In a constituent element for an interwound fabric, in which theelements cohere together and are interlaid, al flattened tube, composedof unwoven flattened threads interwound and `interlaid withv each other,each thread composed of a parallel series of yarns, the finished productsaturated with fluid adhesive material, and provided with an externalcoating of the same.

4. As an article of manufacture, an element from which a fabric can beconstructed, said element comprising a flattened tube composed ofunwoven nterwound and interlaid flattened threads, compressed together,each thread composed of la vseries of parallel yarns loosely associatedtogether,

said flattened band saturated throughout `and between the yarns withfluid rubber, or other adhesive material.
